应用放射性核素及γ照相机、电子计算机测定左心室局部喷血比数,结合握力试验对冠心病的诊断可能提供了一个新的有用的方法。实验和临床研究表明,局部心肌收缩异常是心肌缺血的敏感表现。握力试验比心室造影、冠状动脉造影术易采用,可以准确地估价局部与全部左心室功能。
The application of radionuclide and gamma camera, electronic computer to determine the local left ventricular ejection fraction, combined with grip strength test for the diagnosis of coronary heart disease may provide a new and useful method. Experimental and clinical studies have shown that local myocardial contractility is a sensitive manifestation of myocardial ischemia. Grip test than ventriculography, coronary angiography easy to use, you can accurately estimate the local and total left ventricular function.
